What should you do when approaching a roundabout?

When approaching a roundabout, it is essential to merge with traffic at a reduced speed. This approach allows you to assess the flow of vehicles already circulating within the roundabout and to safely enter without causing disruptions. Merging at a reduced speed enhances your ability to yield to any vehicles that may have the right of way and to navigate the roundabout smoothly.

Observing reduced speed ensures that you can react promptly to any changes in traffic conditions. It also allows you to gauge the gaps in traffic that enable safe entry without forcing other drivers to brake suddenly. Using this method promotes a safe and orderly flow of traffic around the roundabout.

The other options illustrate less appropriate behaviors. For example, speeding up to merge can create hazards, as you may misjudge your entry point and force other vehicles to alter their speed or direction. Stopping before entering is unnecessary and can lead to confusion and unexpected delays if there are no vehicles approaching. Giving way to all vehicles would also be impractical, as roundabouts are designed to allow vehicles already in the roundabout to continue moving, and failing to give way to them could disrupt traffic flow and create congestion.
